Thanks guys.
OK tested the +5volt DC regulator transistor and tested the 2 diodes on the PS board. All test fine. Tested the bridges out of curiosity, both test fine.
Checked driver board and all looks fine...Tested the transistor in the blanking section and it tested fine. Visually checked it too, all good.
Have run out of 4 amp slo blo fuses, so turning the machine on to test the PIA's will have to wait until i can find/purchase some.
